HYDROCARBON-LAMP.

To all whom it may concern:

lamps, and especially to that class in which the gasolene, kerosene, alcohol, or the like, is gasified' and burned in connection with an incandescent mantle; and the objects of my invention are: 1. To provide a lamp of this kind which can be easily kept clean so that it will operate with the highest efii- I ciency; 2. to provide a lamp of this kind I hydrocarbon is gasified, and from which it v is discharged through a very small orifice.

with means to prevent the breakage of the mantle, or mantles in cleaning; 3. to provide an efficient construction in which natural breakage will not cause serious annoyance; 4:. to provide a lamp with ready and simple means for removing the partsv necessary to be cleaned, and the utilization of these means relative to the convenience of putting the lamp in operation; 5. to provide a lamp of this kind with parts so constructed that a cleaning needle can be easily inserted, and, at the same time, the noise in operation will be largely eliminated; and 6. to provide a hydrocarbon lamp that is cheap to manufacture, efficient in use, and attractive in appearance.

In the construction of hydrocarbon lamps using a mantle, or mantles, it is customary to provide a vaporizing tube in which the As this tube is usually Very hot considerable carbonization takes place at this orifice in the dischargenozzle thereby requiring the frequent insertion of a needle to clear the orifice. 7

As usually constructed lamps are provided with two burners and mantles; and it is a very difficult matter to needle the orifice in the nozzle without breaking one, or both of the mantles even if the needling is done through the air intake. If the vaporizing tube is removed from the lamp to needle the same, the breakage of the mantle, or mantles is even more certain.

I have found'it desirable to use wire screens in the air intakes to prevent dirt Specification of Letters Patent.

being drawn into the lamp; and these screens prevent the insertion of a needle in the nozzle orifice through the air-intake, necessitating the removalof the vaporizing tube'each timethe orifice has to be needled,

As the vaporizer must be removed each time, I have provided simple and efficient means to remove and insert the same without I breaking elther mantle; and have also provided simple and efficient means to prevent the annoyance of breakage of a part of the vaporlzer in removlng, or 1nsert1ng,wh1ch r Patented June 15, 1915.

will be hereinafter pointed out. I havealfso provided the vaporizer with simple means to tighten, and unscrew the same without requlring the use of a tool; and have also provided the vaporizer with a nozzle of special construction which will not only lend itself to the easy removal, and insertion of the vaporizer; but which also renders the needling of the same very easy, and atthe same time provides means to reduce the noise of operating the lamp.

The invention is illustrated in the accom- I panying drawing, in which- Figure 1, 1s a side elevatlon, partly 1n section, of a lamp constructed 1n accordance with my invention; Fig. 2, is a front-view,"

partly in section, of the upper portion thereof; and Fig, 3, is a vertical section of the nozzle, mounted on the vaporizing tube.

In the drawing, like numerals of reference refer to the same parts in each of the views, In the drawing I have'shown only the structural part ofthe lamp without reference to a reservoir, or means for holding the hydrocarbon, or feeding the same to the vaporizing tube. As such reservoirs, and

feeding means are. variously constructed, and also well known, any one skilled in the 1 art will understand these parts without illustration. f a I V In practice I iprovidean upper structure consisting of an air-intake 4:, mixing chamber 5, burner tubes 6, 6, carrying mantles 7, 7 and a lower structure consisting of the needle valve casting, f8, with controlling wheel 9, vaporizing tube 10, with nozzle 11 and connection 12, with a reservoirzand I connect the upper and lower structures with a single standard 13, which may be mounted on an arm 14, ofthe needle valve casting, said standard having a featheredconnection 15, to prevent turning, and being secured rigidly in place by a nut 16. The upper structure will thus be held rigidly in place whereby the air-intake will have one entrance directly over the standard 13, and the other entrance on the opposite side of the lamp while the burner tubes and mantles will be held in fixed positions on the opposite sides of said air-intake, and of the vaporizer which enters the air mixer substantially central of the air-intake.

The air -intake has a perforation 17, through which the nozzle 11, of the vaporizer may enter; and the lower end of the vaporizer is provided with the usual reduced screwthreaded part 18, whereby the height of the nozzle within the air mixer may be regulated, as will be readily understood.

Where the reduced part 18, is screwed into a solid casting, or forging, owing to the frailness of the same it is frequently broken, and causes a great deal of trouble in the removal of the portion of the part 18, left in the socket. To avoid this trouble 1 have provided a bushing 19, which 1 mount in the part 8, or in whichever part the vaporizer tube is usually mounted; and I screw the reduced part 18, into this bushing. Thus, if the part 18, should be broken in the socket, 1 can easily remove the bushing 19, and extract therefrom the portion of the part 18, contained therein, or I can substitute a new bushing. I am thus able to remove the vaporizer, and reinsert the same, or renew the same with very little trouble. In order that the vaporizer may be re moved, and reinserted without breaking the mantles, T have provided the end of the airintake piece opposite the standard 13, with a channel 20; and the air-intake piece is also preferably provided with a ledge, or shoulder 21, abutting on the opening 17. Thus, in inserting the new vaporizer, the end is inserted in the channel 20, as indicated in dotted lines in Fig. 1; and then by sliding the vaporizer inward the nozzle will strike against the shoulder 21, which will act as a stop, and also as a guide to direct the nozzle upward through the orifice 17. The lower end of the vaporizer can be then carried inward with little danger of breaking either mantle since the upper end is held rather rigidly; and the part 18, can be screwed into its socket. Thus by having the guiding channel 20, and'the shoulder 21, the vaporizer may be easily removed, and replaced without causing damage to either mantle. It will be understood, however, that this feat is the more readily accomplished owing to tile fact that but a single standard 13, is use V In order that the vaporizer may be more readily entered in the way described, 1 pre fer to provide the nozzle 11, with fiat sides 22; and these sides also furnish ready means for engagement with a wrench to unscrew the nozzle from the vaporizing tube.

In order that the vaporizer may be the more easily removed and reinstated, I prefer to braze, or oth rwise secure on the vaporizer tube a knurled cup 23, which may be used as a starting cup by placing therein asbestos 21, into which alcohol may be poured for burning when starting the lamp. This cup 23, therefore performs the double function of providing a ready means for adjusting, or removing the vaporizer, and of providing a starting cup when putting the lamp into operation.

In order that the nozzle may be readily needled when removed from the lamp, 1 provide a countersunk portion 25, above the orifice 2G; and this countersunk portion will act as a guide for the needle so that the needle can be inserted in the orifice 26, with little difiiculty. This not only adds to the convenience of needling the nozzle, but the countersunk portion allows for the expanding of the gas after passing the orifice but before leaving the nozzle entirely; and this seems to materially lessen the noise of operating the lamp. Inserting the nozzle in the end of the vaporizing tube 10, instead of mounting the same on the end of the tube as a cap, as is generally done, gives more directness to the flow of gas and reduces the noise of operation.

The entire construction works together to form a lamp of great efficiency, desirability, and compactness.
